1 Claim. l

The invention relates to improvements in vapor disseminators, and has for its primary object the provision of an improved construction for the purpose which is simple in construction and highly eiiicient in use.

Other objects will appear hereinafter.

The invention consists of the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification and in Which- Fig. 1 is a side view, shown partially in section, of a container embodying the invention;

Fig. 2, a section taken substantially on line 2 2 of Fig. 1;

Fig. 3, a section taken substantially on line 3 3 of Fig. 1; and

Fig. 4, a section similar to Fig. 3 but showing the parts in positions for disseminating vapors.

The embodiment of the invention illustrated in Figs. 1, 2, 3 and 4 comprises a cylindrical container I which may conveniently be made of cardboard or the like, and is provided in the opposite side walls with perforations II adapted and arranged to cause dissemination of vapors from volatile crystals or the like in said container. A sealing member I2 in the form of a cylindrical sleeve or shell is shiftably mounted upon the exterior of the container I0 so as to be capable of rotation thereon, and is provided with perforations I3 arranged to be brought into and out of registration with the perforations II by relative rotation between said casing and the container. The casing I2 is held upon the periphery of the container I 0 by means of bands I4 and I5 secured respectively around the top and bottom thereof as shown. The band III is provided with a notch I'B and the casing I2 is provided with a projection I1 tting into the notch I6 and arranged to limit the rotations of the casing I2 on the container IU in one direction at the position in which the openings I I and I3 are in registration with each other, and in the other direction in the position in which said perforatlons are out of registration with each other.

In this way a container for volatile substance is provided which may be readily sealed whenever desired, or opened for dissemination of vapors therefrom by simple rotation of the casing I2 on the container IIB, as explained above.

A suitable cap 2! is provided for sealing the container I9, and if desired the container may be equipped with a strap 29 .by Which it may be suspended.

While I have illustrated and described the preferred form of construction for carrying the invention into effect, this is capable of variation and modication without departing from the spirit of the invention. I therefore do not` wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modiiications as fall within the scope of the appended claim.

I claim:

A vapor disseminator comprising: a cylindrical container having perforations in the wall there` of; a cylindrical sealing member encompassing the cylinder side of said container and shiftable thereon, said sealing member having perforations arranged to be brought into registration with said rst mentioned perforations; and means for limiting the shifting of said sealing member in one direction with said perforations in registration and in the other direction with said perforations out of registration, said means comprising an annular band member at one end of the sealing member and an intertting projection and notch on said members.
